Title: Documentation device
Inventor: TANAKA TSUTOMU
IPC: G06F17/21
Filed: 1990-02-09
Abstract: PURPOSE:To simplify table generation procedures by only designating the generation area of a table and the start point of a rule to judge a horizontal or vertical rule, and generating the horizontal or vertical rule from the designated start point thereafter. CONSTITUTION:When the start point of a rule is designated and this start point X is on a line XS or XE, a rule to be drawn is decided as a horizontal rule. A rule generating part 11 generates the horizontal rule of a designated line classification in the position of a work buffer 11 corresponding to the part from the position of the line XS to that of the line XE of the row read out to a one-row buffer 9. When the start point X is not on the line XS neither XE, the rule to be drawn is decided as a vertical rule, and a variable SL is set to a row counter variable ML. A one-row read part 7 reads out the row designated by ML in a text buffer 5 to the one-row buffer 9, and the vertical rule of the designated line classification is generated in the position of a work buffer 12 corresponding to a cursor position X of this read-out row. Thus, the table is easily generated.

Title: Gaseous spring device
Inventor: NAKATSUKA MASAHIKO
IPC: F16F9/08
Filed: 1983-02-25
Abstract: PURPOSE:To make a spring constant alone alterable regardless of pressure in a gas chamber, by making the capacity of the gas chamber adjustable without altering the pressure in the chamber. CONSTITUTION:A main chamber 1 is interconnected through with an air pressure source 5 and an auxiliary chamber 40 making up the air and part of an air chamber via an interconnecting passage installed in the upper part of a piston rod 10. When an air capacity selector valuve 41 is opened, the main chamber 1 and the auxiliary chamber 40 are interconnected with each other whereby the measure of capacity in the air chamber increases as far as a portion for the volume of the auxiliary chamber 40. On the other hand, both these chambers 1 and 40 vary each internal pressure even in time of raising the internal pressure with air taken from the air pressure source 5 as well as in time of bringing it down with an exhaust valve 7 so that their internal pressure will be kept equal all the time. Therefore, a spring constant in the air chamber can be altered by a capacity variation in the air chamber regardless of the internal pressure.

Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity of providing a separate cooling facility by cooling a path of liquefied gas from intake to discharge to a temperature near that of the liquefied gas using a portion of liquefied gas drawn in beforehand. SOLUTION: A cooling chamber 5 is placed on an outer periphery of a cylinder 4. Liquefied gas, for example liquefied carbon dioxide, contained in a gas cylinder 1 is charged into the cooling chamber 5 to cool the cylinder 4. Liquefied carbon dioxide to be compressed is then drawn into the cylinder 4 through an intake hole 19. During this time, a piston 10 is slowly retracted at a speed controlled by a control device 15 so that the internal pressure inside the cylinder 4 becomes almost equivalent to that inside the gas cylinder 1. The piston 10 is thereafter advanced all at once to compress the liquefied carbon dioxide in the cylinder 4. According to this construction, part of the liquefied gas to be compressed is used for self-cooling to cool a compression device 2, allowing a compression capacity to be increased without needing to install a separate cooling facility.
